Hi all,

First of all, sorry for off-topic.

I would like to know if you configure DMVPN, is it necessary to
configure IPSec as "transport" mode. In my situation, some spoke sites
are behind NAT device.
However, NAT is configure 1:1 statically with FW.
I see some CCO Doc explain that it must use "transport" but I really
don't understand why...

Thanks in advance.
